Re: Losing connection when ramping over defenses
We are seeing the same behavior, with both the competition and practice robots. Both robots worked well for the first couple of minutes and now any forceful contact with the defenses causes a loss of comms. We have double checked the fuses, ethernet cables, all connections, main breaker, battery terminals, etc. and cannot find anything questionable. We have wiggled and jiggled all wires and even done drop tests of the robot on all sides and cannot replicate the problem - only when physically driving. I took a high speed video (240fps) of the control board during impact and what I see is this:
Robot impacts the defense, about 10 frames later (about .05s) the RoboRio power light turns orange for a few frames, then back to green for a few frames, then goes dark for about 10-12 frames, then goes back to green.
So it seems to be a power issue to the RoboRio, at least in our case. Lights on all the Talons behaved as normal during this and lights on the router behaved as normal during this.
We will continue to investigate...
